Miss Maya Sinstress had been previously edging Her slave when he's done nothing to earn it. So, now he has to take some pain for Her. She ties up his balls tightly and puts an electro around his balls and the base of his cock. She hooks him up to an e-stim unit and his cock easily responds. His dick bounces around from the pulsation. Soon, all of the muscles in his entire body is twitching. He can't stay hard from the pain, so Sinstress teases his dick with a vibrator. He struggles to endure all the electrical pain and yelps out his safety word.
